Hi, a quick question, if I made small changes (like add just a comma or question mark to my stings), when I update the file with this version, translation I’ve made in past becomes lost, so I need to go 1 by 1 and add translation manually. Is there any option I can update the file without translation progress lost?
Hello, try the “update option”, it should work for you perfectly 
For API you can use the Update option = keep translations:
API v2 Reference
For CLI - update without changes (also same logic works for GitHub integration and similar): Configuration File | Crowdin Documentation
For the UI, the system should show you a pop-up message on the matter, so you can decide whether to leave translations or not:
